TAK-875 (Synonyms: TAK 875;TAK875)

TAK-875 is a potent, selective, and oral GPR40 agonist. GPR40 is one of the G protein-coupled receptors predominantly expressed in pancreatic β-cells, mediating enhancement of glucose-stimulated insulin secretion by free fatty acids.

In vitro: TAK-875 exhibited potent agonist activity and high binding affinity to the human receptor. In addition, TAK-875 showed excellent agonist potency selectivity for GPR40 receptor over other members of the FFA receptor family (for which EC50>10 μM) [1].

In vivo: TAK-875 showed potent plasma glucose-lowering action and insulinotropic action during an oral glucose tolerance test in female Wistar fatty rats with impaired glucose tolerance [2].

Clinical trial: TAK-875 acts as a glucose-dependent insulinotropic agent with low hypoglycemic risk. Its P K is suitable for once-daily oral administration.
